Practical Example 1
[0043]1 g of a silica gel with an average particle size of 5 μm and a specific surface area of 450 mm2 / g was charged into an ampoule and dried at 120° C. and a reduced pressure for 10 hours. After the ampoule was cooled, addition of 0.55 mL of vinylmethyldimethoxysilane and sealing thereof were conducted under nitrogen atmosphere and reaction was conducted at 350° C. for 12 hours. Furthermore, after a product was taken out and washed with 10 mL of chloroform and 10 mL of methanol, drying was conducted at 120° C. and a reduced pressure for 10 hours.
[0044]After 0.7 g of obtained particles were dispersed in 3 mL of dehydrated toluene, addition of 3.1 mL of octadecyldimethylsilane and stirring were conducted. Then, after 14.45 μL of 3 mass % solution of chloroplatinic acid in toluene was added and reaction was conducted at 70° C. for 8 hours, cooling and filtration were conducted. After an obtained residue was washed with 10 mL of chloroform and 10 mL of methanol, dry...

Practical Example 2
[0045]15 g of a silica gel with an average particle size of 5 μm and a specific surface area of 450 mm2 / g was dispersed in 60 mL of dehydrated toluene. Then, after addition of 5.79 mL of pyridine and 3.12 mL of vinyltrichlorosilane and heating and reflux for 3 hours were conducted, cooling and filtration were conducted. An obtained residue was washed with 100 mL of toluene, 100 mL of acetonitrile, and 100 mL of 60 mass % aqueous solution of acetonitrile. Furthermore, dispersion in 100 mL of 60 mass % aqueous solution of actonitrile, stirring at room temperature for 1.5 hours, and filtration were conducted. After an obtained residue was washed with 100 mL of 60 mass % of acetonitrile and 100 mL of methanol, drying at 120° C. and a reduced pressure for 10 hours was conducted. The content of carbon in obtained particles was 4.00 mass %.
[0046]2 g of obtained particles were charged in an ampoule and drying at 120° C. and a reduced pressure for 10 hours was conducted. A...
